From 0c2f51a7d2546f65e4198cccd6a56e2a8b857677 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 30 Jan 2008 13:30:42 +0100 Subject: [PATCH] x86 vDSO: arch/x86/vdso/vdso32 This moves the i386 vDSO sources into arch/x86/vdso/vdso32/, a new directory. This patch is a pure renaming, but paves the way for consolidating the vDSO build logic.
